Select the correct answer.
which equation has no solution?
a.
2.3y + 2 + 3.1y = 4.3y + 1.6+ 1.1y + 0.4

b.
32x + 25 - 21x = 10x

c.
5/8x + 2..5 = 3/8x + 1.5 + 1/4x

d.
1/3 + 1/7y = 3/7y

Equation C: 5/8x + 2..5 = 3/8x + 1.5 + 1/4x

Step-by-step explanation:

Let us go through each of the equations one by one.

Equation A:

This simplifies to

which has infinitely many solutions.

Equation B:

this simplifies to

which is exactly one solution.

Equation C:

this simplifies to

There's no way this is going to be possible; this equation has no solutions.

Equation D:

this gives

which is exactly one solution.

Thus we see that it is equation C that has no solutions.
